Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

A CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) is a program that to tell a human and an automated program apart. The inovation is to design a background with ectopic picture, the picture is split by one or more concentric circles , and made the original picture split like using gear rotating, and then the picture is mismatch with random angle.

A new CAPTCHA and unlock method by rotating concentric circular pictures

A CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) is a program that to tell a human and an automated program apart.

There are some existing ways here, but each of the methodology has drawbacks, especially for the users of mobiles:

1. Inconvenient for the users of mobile to input the characters.

2. Hard to recognize, especially with mobile screen: Twisting characters way to implement the verification, but more ambiguity there, even human couldn't recognize that and waste lots of times to regenerate/guess characters they need to input.

3. There are multi-hierarchy logic there, such as there are lots of Chinese characters and interrupting with a pic. And let human input what the Chinese character expressed by the pic. Human must have known localized characters knowledge and could know the localized culture and programme to understand what they should do.

4. Such as these below pre-art. Some easy or limited image captcha is applied, but the current computer technology, could do some permutation and combination, could point out the solution of the real captcha. And the security couldn't be defensed.

Our invention is to design a background with ectopic picture, the picture is split by one or more concentric circles , and made the original picture split like using gear rotating, and then the picture is mismatch with random angle.

To access the CAPTCHA, users circle their figure on the touch screen, circle gesture, and swivel the gear with correct angle. By Following with the correct swiveling angle for the circle, the picture could be conjunct once again and pass the CAPTCHA test.

The advantage of the invention:

1) Convenient: More convenient for access the CAPTCHA for mobile, since the swiveling couldn't be more better than inputting some number or characters in the mobile screen. As known, handling the mobile keyboard using finger is so hard that more typo error oc...
